Do not need help, this is FYI
I manage a blog running FeedWordPress for a customer. Installed three different "like" button plugins and all work erratically. The Like button was not appearing on all posts.
I finally narrowed it down to a conflict with "syndication_feed_id" When this field is removed from a post, the Like button will show up. Carry on...
The blog I need help with is www.advertisingmiami.com.
